illacloud/deploy/app feedback form seems borken?

I wanted to suggest "xattrs" (extended file attributes), following your links to "Suggest more resource":
https://builder.illacloud.com/illacloud/deploy/app/ILAbx4p1C7Q2

I tried 2 different browsers with all kinds of default-profiles, etc: When I hit submit, nothing happens.

Sorry for barking up a wrong tree here, but I feel a bit helpless: `button says void` :cry: 
Any help appreciated :)
